While b2evolution will always remain Free Open Source Software at its core (see [[http://b2evolution.net/about/about-us About Us]]), it is also a commercial enterprise with 3 different sources of revenue:
1. Self-funded by VIP Support contracts;
2. Long term partnerships with companies who play an active role in the development of the software (e-g: The Evo Factory);
3. Commissions from our Web Hosting partners whom we recommend on our site.
These sources of revenue make b2evolution a profitable, self-funded and sustainable enterprise (since 2007).
Furthermore, these sources of revenue are largely sufficient to keep upcoming releases of b2evolution 100% Free for you to use, modify and/or redistribute (see GNU GPL License) for the long term future.
Historical note: at its beginnings, b2evolution also used to be (partially) funded by donations. This is no longer the case (since 2009).
